Description
Enfys is an IR reflectance spectrometer for ESA’s Rosalind Franklin Rover (planned for launch in 2028), which has undergone rapid development since 2024 to replace the previous ISEM instrument. RAL Space is responsible for the design, analysis and test of Enfys’s electronics box. This has an unusual thermal configuration within the lander, sitting on insulating stand-offs with a dedicated thermal strap for heat rejection.
This presentation will explore the thermal development of the Enfys electronics box. This includes initial feasibility studies to assess the necessity of the thermal strap, the development of the thermal modelling approach (particularly regarding the representation of the convective heat lift from the Martian atmosphere) and the inputs of the thermal model to the instrument CONOPs. More recent test verification of the EQM and FM will also be presented, which has included simulating the thermal configuration within a thermal balance test.
